11 Cable Drum
Object:
Variations of attenuation due to winding quality on cable drums.
First part of the test:
Second part of test:
Third part of the test:
attenuation measurement of perfectly wounded drum
attenuation measurement of unwinded cable
spooling of the cable drum in a typical on stage manner,
i. e. with a lot of crossed cable windings; attenuation
measurement
Test Set-Up:
Test procedure according to chapter 1 Attenuation.
Parameters:
Drum assembly:
Cable length:
Wave length:
NKO2SA-3-1000 - single mode 2 x 9/125µm
1,000 m
1,310 nm
Results:
First test (spooled cable drum): attenuation initial channel A: 0.34 dB
channel B: 0.37 dB
Second test (unwinded cable drum):
change in attenuation - 0.04 dB to - 0.07dB
Third test (spooled cable drum): increase of initial attenuation + 0.01 dB
to + 0.08 dB
